Stranger informs me that she read on the internet that in America 'men in vans' have technology to read your bank cards and the only way to stop them taking all my money is to wrap them in tin foil.
They will target ladies handbags and men's back pockets, she informs me.
AIBU to ignore her and keep my cards in my non-tin-foil purse?
she seems one step away from a tin-foil hat
